是说芯语·2025-10-30 03:34Core Viewpoint - The article emphasizes the importance of unifying instruction set architecture (ISA) for the development of China's computing chips, suggesting that RISC-V should be adopted as a standard to enhance innovation and resource efficiency in the semiconductor industry [5][30]. Group 1: Evolution of Computing Architecture - Over the past 40 years, the development of processor chips has followed a "negation of negation" spiral, oscillating between self-research and abandonment [4]. - The last five years have seen a resurgence of machine and platform manufacturers entering the "chip war," shifting from CPU-centric homogeneous computing systems to heterogeneous computing involving CPUs and xPUs [5]. - The computing evolution has transitioned from centralized processing to distributed systems, with the current core CPUs dominated by x86 and ARM architectures [9][10]. Group 2: Challenges in Architecture Innovation - The article discusses the difficulty of architecture innovation and the greater challenge of building an ecosystem, highlighting that software and collaboration barriers are significant [14]. - The dominance of x86 architecture is attributed to its ability to adapt and expand its instruction set to meet new application demands, while RISC architectures have struggled due to high costs and inability to disrupt existing ecosystems [11][13]. - The article notes that the software development costs significantly exceed hardware costs, making it challenging for new architectures to gain traction in the market [19]. Group 3: Future of RISC-V and ARM - RISC-V faces commercialization challenges despite its potential, with successful applications primarily in simple software scenarios like embedded systems [21]. - The article predicts that x86 CPUs will continue to dominate the server market for the foreseeable future, while ARM's success will depend on its ability to penetrate the x86-dominated landscape [20]. - The article suggests that the future of RISC-V in general-purpose computing will require overcoming significant hurdles, particularly in software and ecosystem development [24]. Group 4: Unified Instruction Set as a Key Pathway - The article advocates for a unified instruction set as a critical pathway for scaling China's computing chips, with cloud service providers being more successful in self-developing chips due to their control over the entire stack [25][26]. - It highlights that successful self-developed chips, like those from Apple, are not just about hardware but also about the integration of software and ecosystem capabilities [27][28]. - The call for RISC-V as a unified instruction system aims to avoid redundant efforts and resource wastage in chip development, promoting a more efficient innovation landscape [30].
